Description

Technical Field

[0001] This utility model relates to the field of toys, and in particular to a remote control for toy cars. Background Technology

[0002] Remote-controlled toy cars are highly playable toys that can also help develop children's hand-eye coordination. Most current toy car remote controls use joysticks, with two joysticks controlling the car's speed and steering respectively. This operation is relatively conventional and requires both hands. Another type of toy car remote control uses a handle-shaped mechanism; the speed is controlled by triggers on the handle, allowing for one-handed operation. However, current toy car remote controls cannot display the speed of the controlled toy car, which somewhat limits their playability. Utility Model Content

[0003] The purpose of this utility model is to provide a toy car remote control, specifically a toy car remote control that can display the speed of the remote-controlled toy car without adding additional control circuitry, thereby effectively improving the playability of the remote-controlled toy car.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a toy car remote control, including a handle and a control trigger, wherein a remote control circuit board is provided inside the handle, a speedometer is provided on the handle, a rotating pointer is provided on the speedometer, a drive mechanism is provided inside the handle, and the control trigger is driven and connected to the speed regulating element on the remote control circuit board and the rotating pointer on the speedometer through the drive mechanism.

[0005] Specifically, the drive mechanism includes a speed control drive unit and a pointer drive unit. The speed control element on the remote control circuit board adopts a rotary resistor or a rotary encoder. The speed control drive unit is fixedly connected to the adjustment rod of the speed control element. The control trigger is fixedly connected to the speed control drive unit. When the control trigger is pulled, the speed control drive unit drives the adjustment rod of the speed control element to rotate. The speed control drive unit is also connected to the pointer drive unit.

[0006] Specifically, the pointer drive unit includes a sliding block and a drive gear. The sliding block is slidably connected to the handle, and a rack is provided on the sliding block and driven by the drive gear. The drive gear is driven by the rotating pointer.

[0007] Specifically, the upper end of the speed control drive unit is equipped with a drive lever and a sliding block for drive connection, and the sliding block is slidably connected to the handle through a return spring.

[0008] Specifically, the handle is equipped with a steering control switch, and the handle is equipped with a steering drive mechanism that is driven and connected to the steering control switch. The steering control switch is electrically connected to the remote control circuit board.

[0009] Specifically, the steering drive mechanism includes a rotary lever and a spare wheel. The rotary lever is rotatably connected to the handle and driven by the steering control switch. The spare wheel is located on the outside of the handle and is fixedly connected to the rotary lever.

[0010] The beneficial effects of this utility model are as follows: By setting a drive mechanism inside the handle, when the control trigger on the handle is pulled, the drive mechanism can simultaneously drive and control the speed adjustment element on the remote control circuit board and the rotating pointer on the speedometer. Thus, when the toy car is remotely controlled by pulling the trigger, the speed of the toy car can be displayed on the handle, effectively improving the playability of the remote control toy car. At the same time, a steering drive mechanism driven by a spare wheel is set on the side of the handle to control the steering of the toy car, which makes it easy to remotely control the toy car with one hand and has high playability.

Detailed Implementation

[0016] Example 1, referring to Figure 1-4 A toy car remote control includes a handle 1 and a control trigger 2. The handle 1 is equipped with a remote control circuit board 3, a speedometer 4, and a rotating pointer 41. The handle 1 is also equipped with a drive mechanism 5. The control trigger 2 is driven and connected to the speed regulating element 31 on the remote control circuit board 3 and the rotating pointer 41 on the speedometer 4 through the drive mechanism 5.

[0017] In this embodiment, when the control trigger 2 on the handle 1 is pulled, the drive mechanism 5 provided in the handle 1 can simultaneously control the speed regulating element 31 on the remote control circuit board 3 and the rotating pointer 41 on the speed dial 4. When the control trigger 2 is pulled, the speed regulating element 31 on the remote control circuit board 3 is triggered, and the wireless module on the remote control circuit board 3 sends a corresponding control signal to control the toy car. At the same time as the control trigger 2 is pulled, it also drives the rotating pointer 41 on the speed dial 4 to rotate, thereby displaying the approximate speed of the toy car.

[0018] The drive mechanism 5 includes a speed control drive unit 51 and a pointer drive unit 52. The speed control element 31 on the remote control circuit board 3 can be a rotary resistor or a rotary encoder. The speed control drive unit 51 is fixedly engaged with the adjusting rod of the speed control element 31. The control trigger 2 is fixedly connected to the speed control drive unit 51. When the control trigger 2 is pulled, it drives the adjusting rod of the speed control element 31 to rotate through the speed control drive unit 51. The speed control drive unit 51 is also driven by the pointer drive unit 52. The pointer drive unit 52 includes a sliding block 521 and a drive gear 522. The sliding block 521 is slidably connected to the handle 1. A rack is provided on the sliding block 521 and is driven by the drive gear 522. The drive gear 522 is driven by the rotating pointer 41. A drive lever 511 is provided at the upper end of the speed control drive unit 51 and is driven by the sliding block 521. The sliding block 521 is slidably connected to the handle 1 through a return spring. When the control trigger 2 is pulled, the speed control drive unit 51 drives the adjustment lever of the speed control element 31 on the remote control circuit board 3 to rotate. Simultaneously, the drive lever 511 at the upper end of the speed control drive unit 51 drives the sliding block 521, causing it to move back and forth. The rack on the sliding block 521 moves back and forth, driving the drive gear 522 to rotate, thereby driving the rotating pointer 41 on the speedometer 4 to rotate. This allows for a rough display of the toy car's speed, improving the playability of the remote control toy car. Since the sliding block 521 is slidably connected to the handle 1 via a return spring, pulling the control trigger 2 causes the sliding block 521 to move, applying force to the return spring. When the control trigger 2 is released, the sliding block 521 returns to its original position under the action of the return spring, causing the control trigger 2 to return to its original position as well.

[0019] In addition, a steering control switch 32 is provided inside the handle 1. A steering drive mechanism 6 is provided on the handle 1 and is driven by the steering control switch 32. The steering control switch 32 is electrically connected to the remote control circuit board 3. The steering drive mechanism 6 includes a rotating lever 61 and a spare wheel 62. The rotating lever 61 is rotatably connected to the handle 1 and driven by the steering control switch 32. The spare wheel 62 is located on the outside of the handle 1 and is fixedly connected to the rotating lever 61. By moving the spare wheel 62 on the outside of the handle 1 to drive the rotating lever 61 to rotate, the steering control switch 32 can be triggered to turn, thereby realizing remote control steering of the toy car. The spare wheel 62 has a large operating radius, which makes it easy to move the spare wheel 62 to control steering while pulling the control trigger 2, facilitating one-handed operation.

[0020] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
